api/instance query performance with 8 vms in rhevm
--------------------------------------------------
Key: DTACLOUD-58
URL: https://issues.apache.org/jira/browse/DTACLOUD-58
Project: DeltaCloud
Issue Type: Bug
Environment: Aeolus-conductor configured for rhevm provider
Rhevm running in Windows 2008 R2 Server with 1.5GB memory VM (running on a
separate blade server)

I noticed that when I had over 7 rhev-h vm's running within rhevm, the CPU was
running > 90% and the api console was practically scrolling continuously. I
looked at the deltacloud-core log file for rhevm and noticed that the query
time of /api/instances were taking > 45 seconds to complete. I started over
adding a single vm every five minutes and noticed that there is a "heartbeat"
from deltacloud-core every 30 seconds, if querying the API is taking longer
than the heartbeat interval, deltacloud-core's heartbeart is causing
performance issues with the rhevm api.
With 8 vm's running, deltacloud-core api/instabces query were timing out and
throwing timeout exceptions.
